T all whom it may concern:

Be it lrnown that il, Moses li/l. Lanus, a citizen ot the United States, residing at Lowell, in the county of Middlesex, State ot Massachusetts, have invented a certain new and useful improvement in Brushes, ol which the following is a specification, reference being had therein to the accompanying drawings.

The invention has relation to brushes, and is more particularly an improvement in brushes ot the class in which the bristles are secured by being clasped between wires that are twisted together, prolongations of said wires having connected therewith and secured thereto the handle ot the brush. @ne type of brush ot this class is shown and described in Letters `Patent ot the United States, No. @bt-4t, granted to nie April 28, i903..

Une general object ot my present invention is to provide in improved manner for connecting and combining a handle with the bristle-carrying wire stem ot a brush ot the class mentioned.

rllhe nature ot the invention will best be understood trom the tollowing description ot certain embodiments thereot chosen tor illustrative purposes and shown in the accompanying drawings, in which;-

ligure l is an elevation, partly in section, ot a brush onthe order of that oi my Letters Patent aforesaid and having the present invention ap lied thereto. 1F ig. 2 shows in central longitudinal section a brush of a diii'erent construction having the invention embodied therein.

Referring first to big. l, the bristles are marked l, the wire stem is shown. at 2, a trough-shaped bach: *constituting what ll term the head ot the brush is designated 3, and a handle is shown at t.. its in the patent reterred to, the bristles l are secured,

in place between the inter-twisted wires forming the steinv 2, the said bristles profecting transversely trom the said steinvand )eing held in place during the twisting ot" the wires by a suitable adhesive, such as pitch, shellac, or the lilre, the said adhesive i serving as an additional securing means tor the bristles atter the completion oli the brush. 'the trough-shaped back 3, as in the patent reterred to, incloses the bristle-holding portion ol` the wire stem 2, and also incloses portions of the bristles adjacent thel wire stem, and clasps said bristles between its edges so as to hold them compressed together.- lThe lower end 5 of the stem is bent back upon itsell", inserted into a hole 6 in the metal back, and clenched securely. tlor'convenience of designation, the metal bach is also as above termed a head, for the purposes ot this case.

lin accordance with the present invention the handle dl is formed with a hole or bore 'i' extending longitudinally therethrough. and at its lower end in Fig. l is formed with a counter-bore 8. rlhe prolongation ot the wire stem 2 extends through the said counter-bore and bore, and the upper end of the troughshaped metal back or head 3, is seated in the counter-bore tl, which it snugly hts. A terrule 9 is applied to the lower end ot the handle, around the portion receiving the upper end of the trough-shaped metal bach. rllhe free extremity ot the wire stein projects at the upper end of the handle and isbent back upon itselt' and clenched at 10, :forming an open eye or loop constituting a suspenslon device by means ot whichthe brush may be hung upon a hook or nail.

lin my patent aforesaid the trough-shaped metal back extends a short distance along the bare portion of the twisted stein above the bristles` but only a traction ot' the distance between the bristles and the handle. .ln the embodiment ot' my present invention shown iny lfig. l the said metal back or head entends t-he whole distance between the bristles and the handle, and is engaged with the handle itsell", as already explained, producing thereby a stitier, stronger, more du rable, and more Satisfactory brush.

rlihe eye or loop l0 formed in the wire stem constitutes a loclr by which the handle and' stem are secured together and the parts ot the brush are held tirmly in proper working relations.

lin the construction shown in Fig. 2 the handle portion l1 is provided with a longitudinal bore 12 and at its lower end in Fig. 2 with a counter-bore i3, while the twisted wire stem it is provided adjacent one end with bristles 15 and is secured in place by bendin the opposite end, which projects trom t e handle portion ll into an open eye or loop lt.l rll`hese lparts all are or may be substantially similar to the corresponding parts of the form ot the invention last described. ln the embodiment illustrated in ltig. 2, however, the trough-shaped back is omitted and the inner portions ot the bristles dii received I directly in the counter-bore 13,

thereby providing an additional hold for the bristles. The mass comprised of the said inner portions of the bristles, immediately adjacent the lower end of the wire stern, gmstitutes the head-portion of the brush of From the foregoin it will be seen that the bristles are secure y held in the stem by mechanical means not depending upon adhesives for its operation, while the stem vis in a similar manner locked in place in the handle. The constructionmoreover is simple and inexpensive and, while secure, 0does not entirely prevent the disassembling ot' the parts should such be desired.

Brushes embodyinthe present invention like that of Letters? atent No.,726,54.4 are designed more especially to be employed in cleaning up dust, lint, etc., upon and around and beneath machinery. In use, they become .charged more or less with grease, oil, and the dust, lint, etc., held thereby. As

a result, the bristles fill up with a stickyv make the said handle of a suitable metal.l l have used aluminum for its lightness.-

After being properly boiled out, the bristles are in good condition, and the brush is ready for continued use. I am enabled to subject the brush to the boiling-out treatment be'- cause of the fact that the bristles are securely held, and the parts locked together, by mechanical means not depending upon adhesives for effective results.

lHaving thus described my invention, I claim 1. A brush comprising a handle having y messen a bore extending lon itudinally therelthrougggh, a stern compose of a pluralit of lengths of wire having bristles clam e between them adjacent one end of t e seid lengths, said stem extending throu h said bore; and having its end opposite said ristles projecting therefrom said projecting end bein bent upon itself against one end of the andle for `securing said stem in said handle, holding the handle immovably upon the stem and the bent portion constituting a suspension eye or loop, substantially as described.

2. A brush comprisin a handle having a bore extendin longitu inally therethrough and a counterore at one end thereof, a stem formed of a plurality of Wires intertwisted throughout their length, and bristles clamped between said wires ad'acent one end of said stem, with the head oi the brush seated in said counter-bore and said stem extending through said bore and having its opposite end projecting therefrom, said rojecting end bein bent against one en of the handle and t ereby locking the handle and stem against endwise movement, substantially as described.

3. A brush comprisin a handle having a bore extending longitu mally therethrough' and provided further with a counter-bore in one of its ends, a stem having bristles secured thereto adjacent one end thereof, said stem extending through said bore with said bristles' adjacent the counter-bored end of said handle, means located at the opposite end of said stem for securing the stem and handle immovabl together, 'and a troughshaped back inc osing the bristle-holdin portion of said stem and portions of sai bristles, ysaid back having a portion seated in said counter-bore, substantially as described.

In testimony whereof I aiiix my signature in presence of two witnesses.
